ELECTRIC HEATER Filed Sept. ,18, 1929 UNITED STATES ELIAS v. CONKLIN,ori-rznw azoaxgn, :Y.-

Application filed September The present invention is directed toimprovements in electric heaters.

The primary object of the invention is to provide a device of thischaracter so constructed that it can be immersed in a quantity of waterto effectively and quickly heat the same.

Another object of the invention is to provide a device of this characterprimarily designed for heating water although not necessarily limited tosuch use since it can be used for various purposes wherein it is desiredto quickly heat a mass or liquid.

Another object of the invention is to provide a device of this characterso constructed that one or more heating units may be used in connectiontherewith.

Another object of the invention is to provide a device of this characterwhich is simple in construction, eflicient in operation and one whichcan be manufactured at a minimum cost.

lVith these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed, andillustrated in the acompauying drawing, in which:

Figure 1 is a side elevation of the device.

Figure 2 is an enlarged vertical sectional view through the heatingchamber.

Figure 3 1S a transverse section through the housing.

Figure 4 is a sectional view on the line 4-4 of Figure 1.

Figure 5 is a detail view of a multiple socket which may be used inconnection with the device.

Referring to the drawing, 1 designates the heating chamber whichcomprises a cylinder,

preferably of tapered formation, said cylinder being formed from copperand having mounted in its lower end a ring 3, said ring being partlyextended from the lower end of the cylinder 2 and being exteriorlythreaded for engaging the rim 4 of the closure cap 5, there being awasher 6 interposed between the lower end of the ring and the bottom ofthe cap in order to prevent leakage.

In the upper end of the cylinder 2 is sea band? which is interiorlythreaded, as at 6,'{ for i threaded? engagement with the 9; saidhoiisi1'1g having mounted the're'ih rackets 10 whichsupporltthe socket11,"am1,:ir is -to this socket that the heating uriit'flQ is Eremovabl-y i'mo'un'ted, there bein a resilient clamp 13 associated withthe socliet to positively; maintain the heating element engagedwherein.-'The housing has formed integral therewith the lower end of the tube14, th'e upperend of'which is closedby a per- Orated Qa MJ *F;ixed tothe up'per end n; the tube 14 isa handle l6iwhichconsists of i-nclined'side members 17* unaware connected with verticalinmberstaLS-which, inturn, are connecte'd by ia'; {cross top bar 19. The handle structure i'shollow' so that-the current con ducting wii es QO may be passedtherethrough and down through the tube 14 for connection withthesocke't; The 'con'ductor'wires are covered with fire-p roofinsulating material. Fig-M6 5 is illu'strated amultiple socket engagingmemberlso that two heating units, as}indicated inudotted lines'at- 21,may be attached tb the socket 11 when desired." It will,'&of-cour'se,'be understood thatthe number of heating units' may be optional and maybeof arly-standard 'make'or' size.

Byproviding thetube-M' at its upper end with the perforated cap 15, theexcessiheat may lbe'gdiseharged .lfrom'theheatingchamher; and; inworries-a protect". the: hands of the operator, a deflecting plate 23 issupported by the handle immediately above the perforated cap.

Since the cap 5 can be readily removed, the heating unit may be removedor replaced as occasion may require, and should the socket become in anyway inefiicient, the housing 9 may be conveniently removed so thatrepairs may be easily made.

From the foregoing, it is thought that the operation and many advantagesof the herein described invention will be apparent to those skilled inthe art without further description and it will be understood that various changes in the size, shape, proportion and minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of the in vention.

hat is claimed is:

1. A heater of the class described comprising a cylinder, a housingthreaded in the upper end of the cylinder for detachable connectiontherewith, a tube rising from the housing and having 'a handle carriedthereby, a socket mounted within the cylinder, circuit wires leadingthrough the handle and tube and connected with the socket, and a capremovably engaged with the lower end of the cylinder. 1

2. A heater of the class described compris ing a cylinder having a cap'detachably con-' nected with its lower end, a housing having threadedengagement with the upper end of the cylinder, a tube rising from thehousing, a handle supported by the upper end of the tube, said tubehaving a perforated cap thereon, a deflecting plate carried by thehandle, and circuit wires passable through the handle and tube, and asocket mounted within the cylinder and connected with the circuit 25wires.

3. A heater of the class described comprising a cylinder, a ring fixedin the lower end of the cylinder, :1 cap threaded upon the ring, a bandfixed to. the upper end of 30 the cylinder, a housing threaded in theband,

brackets carried by the housing, a socket supported by the brackets, aheating unit, engaged in the socket, a tube rising from the housing, ahandle connected with the tube,

35 and circuit wires leading throughthe handle and tube and connectedwith the socket.

4. A heater of the class described comprising a cylindrical heatingchamber, a" tube connected with the heating-chamber, a heat-- ing unitmounted in the chamber, a handle carried by the upper end of the tube,saidtube having a perforated cap in its-upperv end, a deflecting platecarried by the handle, and circuit wires leading through the handle 5and tube and connected with the heating element.

In testimony whereof I afiix my signature.
